Optical Microscope 

  • Light microscope allows you to see the position of the cell membrane, cytoplasm and nucleus in eukaryotic cells. Small organelles are not seen clearly. 
  • Resolution of 200nm, good to see cells not small details of organelles. 

Magnification is how much bigger a sample is under a microscope than in real life. 

  • M = objective lens x eyepiece lens 

Resolution is ability to distinguish between 2 points of an image e.g. the amount of detail it can be limited by the wavelength of radiation used to view the sample. 

Preparation of Slide 

  • Fixing 
  • Dehydration - H2O molecules deflect electron beam
